REUBEN S. OIIAFFEE, OF SPRINGFIELD, ILLINOIS, ASSIGNOR OF ONE-HALF HISRIGHT TO J. N. REEOE, OF SAME PLAGE.

iMPROVEIVIENT IN MAGAZINE FIRE-ARMS.

Specification forming part of Letters Patent No. 212,657, dated February25, 1879; application filed December 19, 187e.

To all whom it may concern:

Be it known that I, REUBEN S. GHAEFEE, of Springfield, in the county ofSangamon and State of Illinois, have invented certain new and usefulImprovements in Magazine Fire-Arms; and I do -hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the vaccompanying drawings,which form part of this specication.

My invention relates to magazine lire-arms, and is intended partially asan improvement uponLetters Patent No. 161,480, granted to me March 30,1875 5 and it consists in the construction of the cut-off or receiverand of the extractor, and also in combining with the extractor amechanism vfor shortening its stroke, whereby the magazine may be outoff, to be held in reserve, While the anni may be still used as a singlebreech-loader, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

Figure l is a vertical sectional view of my invention, shown inconnection with the magazine in the breech. Fig. 2 is an enlarged de,tached view of the same.

In a magazine lire-arm of the class to which my invention appertainsthere are used two loading-bars, one of which is stationary and holdsthe cartridges in position,

while the other has a backward and forward motion, corresponding withthe action of the breech-block as it travels back and forth.

A represents the breech-block, constructed and operating substantiallyin the same manner as described in my former patent, above referred to.

B is the extractor or finger, which slides in slide abe raised theshoulder b on the extractor Will come in contact therewith and stop themovement of the extractor, thus shortening its stroke, and by moving theslide down out ofthe way of the shoulder b will lengthen the stroke.

By this means I can lengthen or shorten the movement of the extractor orfinger, which is in combination with the movable loading-bar, and so cutoff the communication with said sliding bar or thev magazine, so as tohold the magazine in reserve and still use the gun as a singlebreech-loader, having in reserve the magazine for close quarters. n

By pushing up the slide a it will connect the loading-bar with themagazine, and the action of the breech-block back and forth will putacartridge in the receiver, which will drop in front of the block on its-backward motion, carrying the loading-bar with it, and as it goesforward will put another in the receiver, and so on until all thecartridges are f exhausted.

It will be seen that by shortening the stroke or travel'of theloading-bar I keep it from passing under and back of the rims of thecartridges, so that it will not bring any cartridges forward; and byusing a slide or thumb-screw to shorten or lengthen the travel of theextractor or iinger, which works in connection with the hook on theloading-bar, it governs the downward travel of said loading-bar, and socan be made touse or cut off the magazine.

The linger B is made strong and sharp at d on the hook that lits theshell, thus making it an extractor and linger both.

D represents the cut-off or receiver at the front end of the magazine,for the purpose of holding and forcing the, cartridge in front of thebreech-block as it passes downward. This receiver is pivoted at t' asuitable distance from the end, so as to leave a projecting fingenpiece,D', at the front end. By pressing on this linger-piece the rear end ofthe receiver will rise in front of the magazine, so that a cartridge canbe inserted, making a single breech-loader when the magazine is cut off,as

above described.

Having thus fully described my invention, what I claim as new,nnddesiretosecnre by' Letters Patent, is-

1. The slide a, having the clamping-screw C to hold it in position, incombination with the movable breech-block A and the sliding finger B,having the shoulder b, in front ol which the slide catches, so its toshorten the movements of the finger B, substantially as shown anddescribed.

2. The receiver D, pivot-ed at i, and provided at its front end with theprojecting ngerpiece D', `substantially las and Afor the purposes hereinset forth.

In testimony that l cla-im the foregoing I have hereunto set my handthis 13th day of December, 1878.

REUBEN S. CHAFFEE.
